Why does a karate expert suddenly reduce the speed of his hand while striking a slab of ice?
Air has less viscosity than ice.
To put that another way, some of the momentum of the Karatekas hand is transferred to the ice. This is what breaks the ice, if, indeed, the ice breaks. If the ice does not break, all of the momentum is transferred to the ice. This causes the hand to stop. The ice will return some of the momentum, causing the hand to reverse direction and/or break.
Given an alternative, a wise martial artist will strike ice with a tool, rather than with a hand. Given a better alternative, a wise martial artist will not strike ice.
